Specification forming part of Letters JonN G. PERRY, of in the countyof Washington `and State` of provements in. Reapers and Mowers or Grass and I do` hereby detaken in connection part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it. i i

My present invention relates particularly to the construction of thatclass of mowers and cutter-bar is driven `by counter-shaft crossm g from wheel to wheel.

`My invention consists, primarily, in the peculiar arrangement `or Aorganization of the crank-shaft that with the gear-ring of one of the `driving wheels, a secondary improvement consisting in the mechanism, or arfor disconnecting from the cutter mechanism operated thereby. y The drawing represents such of the parts of a machine embodying` the invention as are directly connectedwith my improvements.

Figure l shows these parts in plan, one wheel being shown half in horizontal central section. Fig. 2 is a sectional, elevation of the same. Fig. 3 is a sectional view of the gearing, and

disk and shield covering the same. A denotes the main axle,mounted upon the two wheels b c. d denotes the finger-bar, upon "which reciprocates the cutter -bar, (not showin) said cutter-bar being driven by a crank or wrist pin, e, on a crank -wheeh f, said pin being connected to the cutter-bar by a pitman or other suitable connection.

The crank-wheel is on the end of "a shaft, g, to which and a shoe, h, the fm ger-bar is hinged by two ears, i, so 'that it can be swung up and rJhe shoe 71, extends back from the iinger-bar,

and is hung at its rear end` to the axle A, as seen in Fig. 2, and at its front end' is connect-` ed to a sleeve, L,

on the opposite end of the axle, by a link, m, as seen in Fig. 1, the rear part of the shoe forming abearing vplate or frame, n, suspended Rhode Island,..have invented Implate n.

Patent No. 104,490, dated June 21, 1870.

` from the axle,ffor carrying the gearing that connects the cutter bar shaft g with the driving-wheel gearing.

The shaft g rotates in suitable bearings o on the shoe or hanger-plate fn, and at the rear end of the yshaft is a bevel-pinion, p, meshing into and driven by a bevel-wheel,l q, rotating on or with a short shaft or pin, r stationarilyk secured or rotating in a bear1ng,s, in the lhanger- On the back side lof this bevel-wheel, preferably formed integral with it, is a spur gear or pinion, t, the teetl of which mesh into and are driven by the internal gear-teeth of a gear-ring, u, tting into and revolving in a hub shell or case, fo, in the wheel, this shell consisting of a web extending radially from the hub to the spokes, and a flange which forms the bearing for the ring, the inner face beif desirable, thus increasing the gear-ring, and shielding it from entrance of hay, grain, or dirt.

The gear-ring u is fixed to a web or diskwheel, w, fixed upon the axle A, and the outer or peripheral surface of the wheel has ratchetteeth or notches w, with which a spring pawl or click, y, engages when the machine is moving forward, while at the opposite end of the axle is a ratchet-wheel fixed to the axle, with which engages a spring pawl or click, `z, so

that `the rotation of eitherwheel in a forward rotative movement to the of which drive the pinion t, and, through said pinion and the bevel-gearing p q, rotates the shaft g and reciprocates the cutter-bar. l

In backing the pawls slip over the ratchetteeth, and the gear-ring and axle are not rotated. K

To disengage thecutter-driving mechanism from the driving-wheels, I hang the bearingplate n to the axle, as follows:

At the top ofthe arm j of the bearing-plate is a ring, a?, which ring surrounds an'eccentric-sleeve, b2, placed upon and turning freely around the axle A. At one end of this sleeve is a handle, o2, by turning which the sleeve is turned upon the axle, and the-ring a? is thereby raised or lowered. to the position shown in Fig. 2, the pinion t drops into engagement with the gear-ring u direction imparts gear-ring, the teeth and."

If the lever be turned but if the handle be turned to the position shown in Fig. 3, which denotes a vertical section through a portion of the gear-ring and the axle A, the eccentric raises the bearingplate n and the gears supported by it, and carries the pinion out of engagement with the gear-ring, so that though the gear-ring and' the axle tiun with both or either of the wheels, no working movement is imparted to the rest of the gearing. v

The handle c2 carries a spring latch-pin, d2, which, pressing into one of two holes, e2, locks the gearing Vin position.

It will thus be seen that the machine is compact, exceedingly simple and eifective, and

thatthe mechanism is easy to manipulate and not liable to derangement.

' By adding the scythe, seat, and lever, the machine can be used as a mower, and the cutting apparatus raised or lowered at the will of the driver from the drivers seat, and, by any suitable mechanism, the machinel can be changed from a mower to a reaper, at pleasure.

Instead of placing the bevel-wheel below the axle, as shown in the drawing, .it may be mounted directly upon the axle and be driven from the gear by its piniont,1neshing,into an intermediate pinion, which meshes into, and is driven directly by gear-ring u and, instead of arranging the latch-pin d2 to lock into holes in the pole-brace f2, as seen in Fig. 1, it may be arranged as seen in Fig. 4, the holes being made on a flange on the ring, at the top of the`l1anger-arm n, in which case the handle c2 may be used as the lever by which to raise the finger-bar and cutting mechanism.

Having described my improvement in mowers and rea-pers, I claim- 1'. In combination with the gear-ring u, rigidly iixed to the axle, the cutter-driving mechanism, supported upon the bearing or hanger plate, suspended from the axle A, substantially as shown and described.

2, In combination with the elements of the preceding, the eccentric b2 and lever c2, for throwing the machine in andout of gear, substantially as set forth.
